    • PURPOSE: Environment-friendly insulating oil and a producing method thereof are provided to prevent the high viscosity generation on an electric power apparatus when using tenebrio molitor extract oil. CONSTITUTION: A producing method of environment-friendly insulating oil comprises the following steps: mixing tenebrio molitor extract oil with low molecular weight compound alcohol using an alkali catalyst for the esterification reaction; phase-separating the obtained ester material and glycerine using water and petroleum ether; and evaporating the ester material for removing the alcohol and the moisture. The alkali catalyst is selected from the group consisting of potassium hydroxide, sodium hydroxide, lithium hydroxide, and sodium alkoxide.
